Male sexy associative disorder (MSAD) is the condition when a person (generally female) associates sexy men with one another. As a result, the individual in question is unable to distinguish between two sexy men, and often gets their identities confused. This disorder is more common in parts of East and Southeast Asia, however, there have been documented cases in the United States, Canada and Australia.
